Description

Technical Field

[0001] The invention belongs to the technical field of aluminum strip transportation, and in particular relates to a reel-type aluminum strip unwinding device for producing easy-open can lids. Background Art

[0002] In the existing production of can lids, it is necessary to first unwind the reel-type aluminum strip into an aluminum strip, and then transport the aluminum strip to a punch press to punch out the can lids. Unwinding the reel-type aluminum strip into an aluminum strip requires special unwinding equipment.

[0003] For example, the utility model patent with patent authorization announcement number: CN221821570U discloses an aluminum coil unwinding device that is convenient for replacing aluminum coils, including a support frame, a motor fixedly mounted on the outer side of the support frame, the output shaft of the motor fixedly connected to a turntable located on the inner side of the support frame, one side of the turntable fixedly connected to the unwinding shaft, and a stabilizing component is provided on the support frame; the stabilizing component includes an adjusting screw with one end rotatably connected to the inner side of the support frame, and the outer side of the adjusting screw is threadedly connected to a support block.

[0004] Based on the search of the above patent authorization announcement number and the shortcomings found therein: The existing unwinding device has a horizontal unwinding shaft, so the aluminum coil needs to be placed vertically and coaxially installed on the unwinding shaft to achieve unwinding processing. However, due to the heavy weight of the aluminum coil itself and the fact that the unwinding shaft is installed on one side of the unwinding device, this force-bearing structure limits the number of aluminum coils placed on the unwinding shaft. Therefore, the above factors together result in the existing unwinding device only being able to place one aluminum coil at a time. This means that after unwinding a single aluminum coil, a new aluminum coil needs to be reinstalled on the unwinding shaft before the unwinding device can be used normally. For factories with large daily aluminum coil consumption, the existing unwinding device requires frequent replacement of aluminum coils onto the unwinding shaft, which reduces the overall speed and efficiency of the factory's production of can lids. Summary of the Invention

[0005] In order to solve the problem that the existing unwinding device can only place a single aluminum coil at a time, for factories with a large daily aluminum coil consumption, the aluminum coil needs to be frequently replaced on the unwinding shaft, which reduces the speed and efficiency of the factory's overall production of can lids. The present invention provides a reel-type aluminum strip unwinding equipment for the production of can lids.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A reel-type aluminum strip unwinding equipment for producing easy-open can lids includes a frame, an unwinding motor and an unwinding reel, wherein the unwinding motor is arranged on the frame, and the unwinding reel is rotatably arranged horizontally at the center position of the frame, the output end of the unwinding motor is coaxially connected to the unwinding reel, and the aluminum coil is coaxially arranged on the unwinding reel. Auxiliary units and adjusting rollers are sequentially provided along the direction of aluminum strip conveying, the auxiliary unit includes an auxiliary roller, the auxiliary roller is vertically mounted beside the top of one end of the aluminum coil, when the auxiliary roller conveys the aluminum strip, the end face of the aluminum strip and the end face of the aluminum coil are parallel to each other; the adjusting roller is vertically mounted beside the top of the other end of the aluminum coil, when the adjusting roller conveys the aluminum strip, the end face of the aluminum strip and the end face of the aluminum coil are perpendicular to each other.

[0007] As a preferred technical solution of the present invention, it further includes a driving component, which is arranged behind the adjusting roller along the conveying direction of the aluminum strip, and is used to drive the movement of the aluminum strip.

[0008] As a preferred technical solution of the present invention, the setting height of the adjusting roller is higher than the setting height of the auxiliary roller.

[0009] As a preferred technical solution of the present invention, the unwinding motor works before the driving component; and when the driving component works, the length of the aluminum strip driven by the driving component per unit time is equal to the length of the aluminum strip driven by the unwinding motor per unit time to release the aluminum strip.

[0010] As a preferred technical solution of the present invention, the auxiliary unit further includes a limiting roller, which is arranged next to the auxiliary roller. A limiting space is formed between the limiting roller and the auxiliary roller, and the spacing of the limiting space is equal to the thickness of the aluminum strip.

[0011] As a preferred technical solution of the present invention, the auxiliary unit further includes a flexible roller, which is coaxially sleeved on the auxiliary roller, and the distance between the flexible roller and the limiting roller is smaller than the thickness of the aluminum strip.

[0012] As a preferred technical solution of the present invention, the outer diameter of the flexible roller increases gradually from top to bottom.

[0013] As a preferred technical solution of the present invention, it also includes a lifting assembly, which includes a vertical rod, a horizontal rod and a driving rod. The vertical rod is vertically arranged next to the frame, and the horizontal rod can slide along the axial direction of the vertical rod. The driving rod is arranged on the vertical rod, and the output end of the driving rod is interconnected with the horizontal rod. The auxiliary roller, the limiting roller and the adjusting roller are all arranged on one end of the horizontal rod.

[0014] As a preferred technical solution of the present invention, it also includes an abutment assembly, which includes an abutment block, a hinge rod, an extension block and a return spring, the auxiliary roller is provided with an abutment slot, an extension slot and a rotation slot that are interconnected, the abutment block is telescopically arranged in the abutment slot, the middle end of the hinge rod and the rotation slot are rotatably connected to each other, one end of the abutment block can be slidably arranged at the bottom end of the hinge rod along the axial direction of the hinge rod, one end of the extension block can be slid at the top end of the hinge rod along the axial direction of the hinge rod, and both ends of the return spring are respectively connected to one end of the hinge rod and the auxiliary roller; The top surface of the abutment block is arranged to fit together with the bottom surface of the flexible roller when it is initially deformed. The top surface height of the extension block is the same as the initial bottom surface height of the aluminum strip fitted on the auxiliary roller.

[0015] As a preferred technical solution of the present invention, the abutment assembly also includes two detection modules, which are respectively arranged on both sides of the protruding block close to one end of the flexible roller. When the driving assembly stops working, the vertical center axis plane of the protruding block coincides with the vertical center axis plane of the restricted space.

[0016] The beneficial effects of the present invention are: By providing a rotatable horizontally arranged unwinding disk, the unwinding shaft coaxially arranged on the unwinding disk is arranged vertically, thereby realizing that the aluminum coil can also be placed horizontally and coaxially on the unwinding disk; since the unwinding disk is arranged at the center of the frame, compared with the structural effect of the existing unwinding device in which the aluminum coil is placed on one side, which causes excessive force on one side of the existing unwinding device, this solution can evenly distribute the weight of the aluminum coil on the unwinding disk and the frame, that is, this solution can evenly distribute the weight of the aluminum coil on the unwinding device, so that the unwinding device can carry more loads at a time.

It solves the problem that the existing unwinding device can only place a single aluminum coil at a time. For factories with a large daily aluminum coil consumption, it is necessary to frequently replace the aluminum coils on the unwinding shaft, which reduces the speed and efficiency of the factory's overall production of can lids.

[0020] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0021] See also Figure 1-Figure 5The present embodiment provides a reel-type aluminum strip unwinding equipment for the production of easy-open can lids, comprising a frame 1, an unwinding motor 2 and an unwinding disc 3. The unwinding motor 2 is arranged on the frame 1, and the unwinding disc 3 is rotatably arranged horizontally at the center position of the frame 1. The output end of the unwinding motor 2 is coaxially connected to the unwinding disc 3, and the aluminum coil is coaxially arranged on the unwinding disc 3; this solution is provided with a rotatable horizontal unwinding disc 3, so that the unwinding shaft coaxially arranged on the unwinding disc 3 is arranged vertically, thereby achieving the aluminum coil can also be placed horizontally and coaxially on the unwinding disc 3; since the unwinding disc 3 is arranged at the center position of the frame 1, compared with the aluminum coil being placed on one side of the existing unwinding device, the existing unwinding device is subjected to excessive force on one side and cannot place multiple aluminum coils at the same time. As a result, this solution can evenly distribute the weight of the aluminum coil on the unwinding disk 3 and the frame 1, that is, this solution can evenly distribute the weight of the aluminum coil on the unwinding device, so that the unwinding device can carry a larger number of aluminum coils at a time. It should be noted that several aluminum coils are coaxially stacked on the unwinding disk 3 from top to bottom. When the top aluminum coil is unwound, the adjacent bottom aluminum coil is directly used, which can reduce the number of times the aluminum coils are transported, save the time of transporting the aluminum coils multiple times, and achieve the purpose of improving the overall speed and efficiency of the factory's production of can lids, and solve the problem that the existing unwinding device can only place a single aluminum coil at a time. For factories with a large daily aluminum coil consumption, it is necessary to frequently replace the aluminum coils on the unwinding shaft, which reduces the overall speed and efficiency of the factory's production of can lids.

[0022] At the same time, it is worth mentioning that there is another reason why the existing unwinding device places the aluminum coil vertically, that is, along the direction of transportation of the aluminum strip, the punch press is set behind the unwinding device, and the function of the punch press is to punch the aluminum strip into the basic prototype of the can lid; since the aluminum coil is in a vertical state, the end surface of the unwound aluminum strip is horizontal, and the horizontal end surface of the aluminum strip is parallel to the output end surface of the punch press. Therefore, the horizontal aluminum strip can be directly transported to the punch press for processing; while the aluminum coil is in a horizontal state, the end surface of the unwound aluminum strip is vertical, and the vertical end surface of the aluminum strip is perpendicular to the output end surface of the punch press. Therefore, the vertical aluminum strip cannot be directly transported to the punch press for processing. The aluminum strip is directly transported to the punch press for processing. Based on this, the present invention is provided with an auxiliary unit 4 and an adjusting roller 5 in sequence along the direction of aluminum strip conveying. The auxiliary unit 4 includes an auxiliary roller 401, which is rotatably mounted beside the top of one end of the aluminum coil. When the auxiliary roller 401 conveys the aluminum strip, the end face of the aluminum strip and the end face of the aluminum coil are parallel to each other; the adjusting roller 5 is rotatably mounted beside the top of the other end of the aluminum coil. When the adjusting roller 5 conveys the aluminum strip, the end face of the aluminum strip and the end face of the aluminum coil are perpendicular to each other; by providing the adjusting roller 5, the aluminum strip of the horizontal aluminum coil is converted from vertical to horizontal, and the horizontal aluminum strip is continuously conveyed to the punch press, so that the punch press can realize the stamping processing of the aluminum strip.

[0023] In addition, it is worth mentioning that in large factories that use aluminum coils to make can lids, the weight of the aluminum coils is usually as high as several hundred kilograms or even thousands of kilograms. Due to the small diameter of the can lids, the width of the aluminum strip used to make the can lids is also relatively small. Therefore, the aluminum coils used to make can lids have the characteristics of large overall weight and small aluminum strip width. In order to facilitate the stacking of such aluminum coils, several aluminum coils are usually stacked horizontally to maximize the storage of aluminum coils.

[0024] However, since the existing unwinding device requires the aluminum coil to be placed vertically on the unwinding shaft, before the aluminum coil is installed on the unwinding shaft, a worker needs to use a lifting device to convert the aluminum coil from a horizontal state to a vertical state, and then use a conveying device to transport the vertical aluminum coil to the existing unwinding device for installation; while the unwinding equipment using this solution can directly use the conveying device to lift the aluminum coil and place it on the unwinding disk 3 without changing the state of the aluminum coil, saving the step of using the lifting device to change the state of the aluminum coil. Therefore, in terms of transporting the aluminum coil, the unwinding equipment of this solution can also save a lot of time compared with the existing unwinding device.

[0025] Specifically, in order to realize the conveying of the aluminum strip, this solution also includes a drive assembly 6. Along the conveying direction of the aluminum strip, the drive assembly 6 is arranged behind the adjustment roller 5 and is used to drive the movement of the aluminum strip. The drive assembly 6 is located between the punch press and the adjustment roller 5 and is used to drive the aluminum strip onto the punch press.

[0026] According to the description of the above embodiment, the central axis of the auxiliary roller 401 of this solution is in a mutually perpendicular or mutually inclined cooperation relationship with the surface of the unwinding disk 3; and the setting height of the aluminum coil is lower than the setting height of the auxiliary roller 401. Since the aluminum coil is located at the bottom of the auxiliary roller 401, and the setting relationship of the auxiliary roller 401 itself, the aluminum strip slides from the aluminum coil to the auxiliary roller 401. Due to the effect of gravity, the aluminum strip will slide toward the bottom direction of the auxiliary roller 401 relative to the auxiliary roller 401. In order to solve this problem, the adjusting roller 5 of this solution is located at the bottom of the aluminum coil relative to the auxiliary roller 401. 401 , and the adjusting roller 5 is set at a higher height than the auxiliary roller 401. With such a setting, when the aluminum strip slides from the auxiliary roller 401 to the adjusting roller 5, since the adjusting roller 5 is set opposite to the auxiliary roller 401, the aluminum strip will partially stick to the auxiliary roller 401 and slide while passing through the auxiliary roller 401, thereby increasing the friction between the aluminum strip and the auxiliary roller 401, and preventing the aluminum strip between the aluminum coil and the auxiliary roller 401 from sliding toward the bottom of the auxiliary roller 401 relative to the auxiliary roller 401 due to the effect of gravity. At the same time, it should also be noted that since the setting height of the adjusting roller 5 in this scheme is higher than the setting height of the auxiliary roller 401, and the transportation direction of the aluminum strip is from the auxiliary roller 401 to the adjusting roller 5, the aluminum strip located between the auxiliary roller 401 and the adjusting roller 5 has a force that lifts it toward the top. This part of the aluminum strip can then provide an upward force for the aluminum strip attached to the auxiliary roller 401, thereby reducing the influence of gravity on the aluminum strip between the aluminum coil and the auxiliary roller 401, and further preventing the aluminum strip between the aluminum coil and the auxiliary roller 401 from sliding toward the bottom of the auxiliary roller 401 relative to the auxiliary roller 401 due to the effect of gravity.

[0027] According to the description of the above embodiment, it can be known that due to the setting of the auxiliary roller 401 and the adjusting roller 5, the aluminum strip is transformed from a vertical state to a horizontal state. Therefore, along the transportation direction of the aluminum strip, the position where the aluminum strip is transformed from a vertical state to a horizontal state is located between the auxiliary roller 401 and the adjusting roller 5. In this scheme, the aluminum strip between the auxiliary roller 401 and the adjusting roller 5 is defined as a transformed aluminum strip; since the transformed aluminum strip is twisted from a vertical state at one end to a horizontal state at the other end, there is also a transition state between the transformed aluminum strips, and the aluminum strip in the transition state has a large torsional stress; at the same time, the driving component 6 of this scheme is used to convey the aluminum strip, and the unwinding motor 2 is used to unwind the aluminum strip of the aluminum coil. In existing equipment, the length of the aluminum strip driven by the driving component 6 per unit time is usually equal to the length of the aluminum strip driven by the unwinding motor 2 per unit time to release the aluminum strip. Such a setting can ensure The unwinding motor 2 is operated before the unwinding disc 3 is driven to rotate, and the unwinding disc 3 is driven to rotate for a long time, so that the unwinding motor 2 can move the unwinding disc 3 at a relatively slow speed.

[0028] According to the description of the above embodiment, it can be seen that since the unwinding motor 2 of this solution works before the driving component 6, the length of the aluminum strip between the aluminum coil and the auxiliary roller 401 is greater than the path length between the aluminum coil and the auxiliary roller 401, which causes the aluminum strip to be unable to fit on the auxiliary roller 401, or the force of the aluminum strip fitting on the auxiliary roller 401 becomes smaller, and the aluminum strip slides relative to the auxiliary roller 401 toward the bottom direction of the auxiliary roller 401; Based on this, in order to solve this problem, the auxiliary unit 4 of this solution also includes a limiting roller 402, and the limiting roller 40 2 is provided beside the auxiliary roller 401, and a restricted space is formed between the restricting roller 402 and the auxiliary roller 401, and the spacing of the restricted space is equal to the thickness of the aluminum strip; by providing the restricting roller 402, a restricted space is formed between the restricting roller 402 and the auxiliary roller 401. Since the spacing of the restricted space is equal to the thickness of the aluminum strip, it can be ensured that the aluminum strip will adhere to the auxiliary roller 401 when passing through the restricted space, thereby preventing the aluminum strip adhered to the auxiliary roller 401 from sliding relative to the auxiliary roller 401 toward the bottom of the auxiliary roller 401.

[0029] It should be noted that due to the setting of the restricted space, the length of the aluminum strip between the aluminum coil and the auxiliary roller 401 will be greater than the path spacing between the aluminum coil and the auxiliary roller 401; and the length of the aluminum strip between the auxiliary roller 401 and the adjusting roller 5 is equal to the path spacing between the auxiliary roller 401 and the adjusting roller 5.

[0030] Furthermore, in order to increase the force between the aluminum strip and the auxiliary roller 401 of this scheme, the auxiliary unit 4 of this scheme also includes a flexible roller 403, which is coaxially sleeved on the auxiliary roller 401, and the distance between the end face of the flexible roller 403 close to the limiting roller 402 and the limiting roller 402 is less than the thickness of the aluminum strip; through such a setting, when the aluminum strip passes through the restricted space, it will press the flexible roller 403, increasing the friction between the aluminum strip and the flexible roller 403, ensuring that when the aluminum strip passes through the restricted space, the aluminum strip will not slide relative to the bottom of the auxiliary roller 401.

[0031] In addition, it should be noted that the converted aluminum strip located between the auxiliary roller 401 and the adjusting roller 5 has an end face of the aluminum strip at one end parallel to the end face of the side wall of the aluminum coil, and an end face of the aluminum strip at the other end perpendicular to the end face of the side wall of the aluminum coil. Therefore, the converted aluminum strip rotates from one end to the other. Specifically, there is a rotation point between the top and the bottom of the converted aluminum strip. The converted aluminum strip moves from the end close to the auxiliary roller 401 to the end close to the adjusting roller 5. At the same time, the converted aluminum strip also rotates around its own rotation point. From the cross-section of the converted aluminum strip, the top of the converted aluminum strip rotates in the direction away from the flexible roller 403, while the bottom of the converted aluminum strip rotates in the direction close to the flexible roller 403. 403, and the top of the rotating aluminum strip is pressed against the flexible roller 403. This arrangement causes the deformation of the bottom of the flexible roller 403 to be greater than the deformation of the top of the flexible roller 403, thereby increasing the probability that the converted aluminum strip will slide relative to the bottom of the flexible roller 403 during the sliding process of the converted aluminum strip against the flexible roller 403. Based on this, the outer diameter of the flexible roller 403 in this scheme increases gradually from top to bottom, thereby further increasing the resistance of the converted aluminum strip when it slides relative to the bottom of the flexible roller 403, and reducing the probability that the converted aluminum strip will slide relative to the bottom of the flexible roller 403.

[0032] According to the description of the above embodiment, it can be known that the unwinding disk 3 of this scheme can carry multiple aluminum coils at the same time. The multiple aluminum coils are coaxially arranged with each other, and the aluminum coils are coaxially connected to the unwinding disk 3. Therefore, when the unwinding process of the top aluminum coil is completed, the unwinding process of the remaining top aluminum coils will begin. In order to ensure that the height difference between the auxiliary roller 401 and the new aluminum coil is the same as the height difference between the auxiliary roller 401 and the original aluminum coil, this scheme is also provided with a lifting component 7. The lifting component 7 includes a vertical rod 701, a horizontal rod 702 and a driving rod 703. The vertical rod 701 is vertically arranged next to the frame 1, and the horizontal rod 702 can slide along the axial direction of the vertical rod 701. The driving rod 703 is arranged on the vertical rod 701, and the output end of the driving rod 703 is interconnected with the horizontal rod 702. The auxiliary roller 401, the limiting roller 402 and the adjusting roller 5 are all arranged on the horizontal rod 702. At one end of the horizontal rod 702, through such an arrangement, when the original aluminum coil has completed the unwinding process, the driving rod 703 will control the height of the horizontal rod 702 to descend, thereby causing the auxiliary roller 401, the limiting roller 402 and the adjusting roller 5 arranged on the horizontal rod 702 to descend together, thereby achieving the relative height between the auxiliary roller 401, the limiting roller 402 and the adjusting roller 5 and the new aluminum coil and the relative height between the auxiliary roller 401, the limiting roller 402 and the adjusting roller 5 and the original aluminum coil. It is ensured that the aluminum strip of the new aluminum coil can be normally conveyed to the auxiliary roller 401 and the adjusting roller 5. It is worth noting that the adjusting roller 5 of this scheme is horizontally arranged, and the output end of the driving component 6 is also horizontally arranged. When the position of the adjusting roller 5 changes in height relative to the output end of the driving component 6, it will not affect the transportation of the aluminum strip between the output end of the driving component 6 and the adjusting roller 5.

[0033] Furthermore, when the factory stops conveying the aluminum strip, that is, when the driving component 6 stops working, the aluminum strip between the auxiliary roller 401 and the adjusting roller 5 will no longer have the force to lift it toward the top, thereby weakening the force of the aluminum strip and the auxiliary roller 401 to fit each other. Therefore, there is a situation where the aluminum strip located in the restricted space will slide relative to the bottom of the auxiliary roller 401 after the driving component 6 stops working. Based on this, in order to solve this problem, the present solution also includes an abutment component 8, which includes an abutment block 801, a hinged rod 802, an extension block 803 and a reset spring 804. The auxiliary roller 401 is provided with an abutment slot 4011 and a rotation slot 4013. The abutment slot 4011 and the rotation slot The holes 4013 are interconnected, the abutment block 801 is retractably arranged in the abutment slot 4011, the hinge rod 802 is arranged in the rotation slot 4013, the middle end of the hinge rod 802 and the rotation slot 4013 are rotatably connected to each other, one end of the abutment block 801 can be slidably arranged at the bottom end of the hinge rod 802 along the axial direction of the hinge rod 802, and the other end of the abutment block 801 can lock or release its matching relationship of shrinking into the abutment slot 4011, the abutment block 801 is arranged at the bottom of the flexible roller 403, and the top surface of the abutment block 801 and the bottom surface of the flexible roller 403 when the flexible roller 403 is initially deformed are arranged in contact with each other; the auxiliary roller 401 is also provided with an extension slot 4012, and the extension slot 4012 is connected to the rotation slot 4013. The slots 4013 are interconnected, and the extending block 803 is slidably arranged in the extending slot 4012. One end of the extending block 803 can slide on the top of the hinge rod 802 along the axial direction of the hinge rod 802, and the extending block 803 can lock or release its matching relationship extending out of the extending slot 4012. The return spring 804 is arranged in the rotating slot 4013, and the two ends of the return spring 804 are respectively connected to one end of the hinge rod 802 and the auxiliary roller 401. The top surface height of the extending block 803 is the same as the initial bottom surface height of the aluminum strip attached to the auxiliary roller 401, and the initial end surface of the extending block 803 is in contact with the flexible roller 403. Through such an arrangement, when the driving component 6 stops working, if the attached After the aluminum strip on the auxiliary roller 401 slides relatively along the bottom of the auxiliary roller 401, the aluminum strip on the auxiliary roller 401 presses the flexible roller 403 in the direction of gravity due to the structure of the outer diameter of the flexible roller 403 gradually increasing from top to bottom, thereby causing the flexible roller 403 to deform toward the bottom of the auxiliary roller 401. Since the abutment block 801 is provided at the bottom of the flexible roller 403, and the top surface of the abutment block 801 is in contact with the bottom surface of the flexible roller 403 when it is initially deformed, when the flexible roller 403 undergoes a secondary deformation toward the bottom of the auxiliary roller 401, the secondarily deformed portion of the bottom of the flexible roller 403 presses the abutment block 801 to slide toward the abutment slot 4011.The abutment block 801 then drives the hinged rod 802 to rotate, causing the top end of the hinged rod 802 to rotate toward the extension slot 4012, thereby driving the extension block 803 to slide out of the extension slot 4012. The extension block 803 presses against the flexible roller 403, increasing the friction between the flexible roller 403 and the aluminum strip, preventing the aluminum strip within the restricted space from sliding further toward the bottom of the auxiliary roller 401.

[0034] It is worth noting that the hinge rod 802 of this embodiment is initially tilted, i.e., the top of the hinge rod 802 is positioned away from the extension slot 4012. Furthermore, the function of the return spring 804 is to reset the hinge rod 802 under the action of the return spring 804 after the height of the aluminum strip is readjusted, causing the abutment block 801 to extend out of the abutment slot 4011 again and the extension block 803 to retract into the extension slot 4012.

[0035] It should also be noted that the flexible roller 403 in this embodiment undergoes two deformations. The first deformation of the flexible roller 403 occurs when the device is operating normally and the aluminum strip is in normal contact with the flexible roller 403. After the deformation, the bottom surface of the flexible roller 403 and the top surface of the abutment block 801 are in contact with each other, and the bottom surface of the aluminum strip is at the same level as the top surface of the extension block 803. The second deformation of the flexible roller 403 occurs when the device stops operating. Due to gravity, the aluminum strip may slide relative to the bottom of the auxiliary roller 401. At this time, the secondarily deformed flexible roller 403 presses the abutment block 801, causing the abutment block 801 to slide into the abutment slot 4011.

[0036] Furthermore, in order to facilitate the secondary deformation of the flexible roller 403 to press the abutment block 801, so that the abutment block 801 slides into the abutment slot 4011, the part of the abutment block 801 extending out of the abutment slot 4011 in this solution is arranged at an angle, and the vertical height of the abutment block 801 gradually increases along the direction of sliding in the abutment slot 4011. Such an arrangement ensures that after the flexible roller 403 undergoes secondary deformation, the part of the flexible roller 403 that undergoes secondary deformation will press the abutment block 801, so that the abutment block 801 slides into the abutment slot 4011.

[0037] As can be seen from the description of the above embodiment, due to the provision of a confined space and the fact that the unwinding motor 2 operates before the drive assembly 6, the length of the aluminum strip between the aluminum coil and the auxiliary roller 401 is greater than the distance between the two rollers. The length of the aluminum strip between the auxiliary roller 401 and the regulating roller 5 is equal to the distance between the two rollers. Therefore, the force exerted by the aluminum strip between the aluminum coil and the auxiliary roller 401 on the flexible roller 403 near the confined space is less than the force exerted by the aluminum strip between the auxiliary roller 401 and the regulating roller 5 on the flexible roller 403 near the confined space.

[0038] In addition, according to the description of the above embodiment, when the driving assembly 6 stops working, the aluminum strip attached to the auxiliary roller 401 will slide relative to the bottom of the auxiliary roller 401. On the one hand, this is because the adhesion force between the aluminum strip and the flexible roller 403 is reduced; on the other hand, this is because the weight of the aluminum strip is too heavy. The above embodiment has solved the problem of reduced adhesion force between the aluminum strip and the flexible roller 403 after the driving component 6 stops working, and the reason for the excessive gravity of the aluminum strip is that the length of the aluminum strip between the aluminum coil and the auxiliary roller 401 is greater than the path spacing between the aluminum coil and the auxiliary roller 401 because the unwinding motor 2 works before the driving component 6; based on this, in order to solve this problem, the unwinding motor 2 needs to rewind the excess aluminum strip after the driving component 6 stops working. However, in the process of rewinding the excess aluminum strip, the unwinding motor 2 cannot pull the converted aluminum strip to move due to the presence of the converted aluminum strip, that is, the unwinding motor 2 cannot drive the auxiliary roller 401 to rotate during the winding process; otherwise, irreversible deformation of the converted aluminum strip will be caused. In order to solve this problem, the abutment component 8 of this solution also includes two detection modules 805, which are respectively arranged on both sides of the protruding block 803 close to one end of the flexible roller 403. The vertical center axis surface of the protruding block 803 coincides with the vertical center axis surface of the restricted space. The left detection module 805 is used to detect the pressing force of the aluminum strip between the aluminum coil and the auxiliary roller 401 on the left end of the flexible roller 403, and the right detection module 805 is used to detect the pressing force of the aluminum strip between the auxiliary roller 401 and the adjusting roller 5 on the right end of the flexible roller 403. The force exerted by the aluminum strip between the aluminum coil and the auxiliary roller 401 on the flexible roller 403 close to the restricted space is less than the force exerted by the aluminum strip between the auxiliary roller 401 and the adjusting roller 5 on the flexible roller 403 close to the restricted space. At this time, the unwinding motor 2 is controlled to perform the winding process until the force exerted by the aluminum strip between the aluminum coil and the auxiliary roller 401 on the flexible roller 403 close to the restricted space is equal to the force exerted by the aluminum strip between the auxiliary roller 401 and the adjusting roller 5 on the flexible roller 403 close to the restricted space. Then the unwinding motor 2 stops working, and the unwinding motor 2 completes the winding process of the aluminum strip.

[0039] It should also be noted that in order to ensure that the vertical center axis surface of the protruding block 803 coincides with the vertical center axis surface of the restricted space when the driving component 6 stops working, the abutment component 8 of this solution also includes a positioning module. The positioning module is arranged in the auxiliary roller 401. The positioning module is communicated with the driving component 6. The positioning module is used to determine the position of the protruding block 803. When the protruding block 803 reaches the specified position, the driving component 6 is allowed to stop working.
